Description

TECHNICAL FIELD

DETAILED DESCRIPTION

Current arrangements for apparel compute devices include integrating everything into a garment or integrating sensors directly into the garment with conductive traces leading to a removable computing device or hub. A removable hub may allow for ease in charging a battery, for example, as well as reducing manufacturing costs by, for example, not having to guard against a washing environment (e.g., the hub is removed prior to washing the garment). Hub connections in removable arrangements are typically achieved via two or more conductive snap connectors or a pocket sewn into the garment and a wired connection.

As wearable computing devices become smaller and more tightly integrated with garments, there is a need for an attachment method that holds the compute device securely without using connecting snaps prevalent in the industry because snaps tend to be large with respective to fabric surface area as well as “high” or “tall” holding the compute device away from the fabric surface. These problems with current fastening devices may be addressed via a magnetic coupling with a physical arrangement to enforce an orientation of the apparel compute device and the garment. Thus, the drawbacks of snaps are avoided while still maintaining the detachable nature of the apparel compute device as well as enforcing positional arrangements to improve performance of the apparel compute device when attached to the garment. Typically, however, power (e.g., a battery) is provided as part of the removable compute devices. When a battery is spent, generally, the entire compute device is serviced or replaced.

As new, lightweight electronic components with small profiles continue to be developed, permanent integration in garments will become more commonplace. A constant, however, is providing power to integrated components. Thus, what is needed is a power module for e-textiles that is serviceable by a user to replace or recharge the battery. In an example, a button cell battery (e.g., coin cell battery, watch battery, etc.) is housed in a conductive cap that directs power and ground directly to a magnetized seat. The seat comprises a set of concentric rings that alternate between insulating and conducting materials (e.g., fabrics) that may be adhered (e.g., is heat pressed) to an e-textile. A magnet (e.g., strong and thin) is bonded inside the garment opposite the seat, which magnetically holds the battery in place. This assembly enables electronics integration into very thin fabrics, such as spandex or other stretchable knit structures.

FIGS. 1A and 1B illustrate use of the e-textile power module with a shirt, according to an embodiment. FIG. 1A is a front view of the inside of a shirt. The seat 105A connects to e-textile traces. In an example, the seat 105A holds a magnet. The seat 105 passes traces through the fabric or fabrics of the shirt to the back, illustrated in FIG. 1B. The rear-view of the seat 105B includes concentric insulating and conducting rings. Here, the shaded rings 110 and 115 are the conductive rings. The magnetic battery housing 120 is held onto the seat 105B via a magnet and electrically connects a positive and negative pole of a battery within the housing to conductive inner circle 110 and conductive inner circle 115 respectively.

The e-textile power module includes three components. Second, the e-textile power module includes a battery housing with battery. Second, the e-textile power module includes a conductive fabric node seat 105 with electronic traces leading to the garment sensing system. Third, the e-textile power module includes a magnet, permanently or removeably, integrated into the garment to securely hold the battery. The battery housing includes positive and negative contacts exposed on a single side (e.g., on a side facing the seat 105 when attached) that align to the magnetic seat and supply power to the e-textile system.

The node seat 105 is permanently bonded to the fabric and provides a stable conductive base for connecting the battery to the e-textile system. As noted above, the node seat 105 comprise concentric rings that align to the power and ground of the battery housing when attached. The conductive fabric is permanently bonded to the garment with an adhesive. Materials such as metallized sealant films (e.g., Bemis EXOFLEX film) may be used for this purpose. The conductive pathways (e.g., traces) are passed through the garment fabric via slits or holes to enable connection to the internal sensing system. The magnet may be permanently bonded or sewn inside the garment directly behind the node seat 105. Additional details and examples are described below.

FIG. 2 illustrates a bottom view of an assembled battery base 205, according to an embodiment. From this perspective of the battery base 205 assembled and holding a button cell battery, the conductive ring 210 is on the outside, the insulating layer forms a second concentric circle and the negative pole 220 of the button battery is exposed via the lumen in the insulating layer. The conductive cap (not visible) contacts the positive pole of the button battery and is electrically connected to the conductive ring 210. Thus, the conductive ring 210 provides an electrical connection to the positive pole of the button battery while the button battery's negative pole 220 is exposed on the same side of the battery housing 205.

FIG. 3 illustrates an exploded assembly of an e-textile power module, according to an embodiment. The battery housing 305 includes a conductive ring 210, an insulating layer with a lumen 215 and a conductive cap 305. The insulating layer 215 is arranged to permit contact of a first battery terminal (e.g., the negative pole) of a battery 310 via the lumen and a second lumen of the conductive ring. Thus, the negative pole of the battery 310 is exposed through the insulating layer 215 and the conductive ring as illustrated in FIG. 2.

The conductive cap 305 is arranged to engage to the conductive ring 210 to hold the battery 310 against the insulating layer 215 against the conductive ring 210 as illustrated in FIG. 3. The conductive cap 305 is also arranged to electrically connect to the conductive ring and to electrically connect to a second terminal (e.g., the positive pole) of the battery 310 when the battery 310 is placed within the battery housing.

In an example, the conductive ring 210 is magnetic or includes a magnetic component. In an example, the conductive cap 305 is magnetic or includes a magnetic component. In an example, the battery housing 350 includes a magnetic component (not shown). In this example, the magnetic component does not impair electrical connections to the battery 310 of either the conductive ring 210 or the conductive cap 305.

As illustrated in FIG. 3 and described above, the conductive cap 305 and the conductive ring 210 are arranged to hold a button cell battery. Other example configuration may operate on other battery configurations however, by connecting—for example by wire or by conductive cap 305 and conductive ring 210 modification—the positive pole to the exterior conductive surfaces and the negative pole to a conductor in the bottom surface (the surface that interfaces with the seat 315).

In an example, the conductive ring 210 and conductive cap 305 are arranged to be repeatedly engaged. Example repeated engagement designs may include a fastener (e.g., clip, screw, magnetic, etc.) or a complimentary concave and convex feature on the two parts. In an example, the conductive ring 210 and the conductive cap 305 are bonded (e.g., with an adhesive, welded, braised, etc.).

The base 360 for the battery housing 350 includes a seat 315. The seat 315 includes an insulating outer circle 316 disposed on a first side of a fabric 320, a conductive first inner circle 317 placed within (e.g., radially inward and wholly enclosed by) the outer circle 316, an insulating second inner circle 318 placed within the first inner circle 317, and a conductive third inner circle 319 placed within the second inner circle 318. Although the term circle is used here, the outer circle 316, the first inner circle 317, and the second inner circle 318 may be other shapes that maintain electric isolation between the first inner circle 317 and the third inner circle 319.

The base 360 also includes a first trace electrically connecting the first inner circle 317 to e-textile wiring 325 through the fabric 320 and a second trace electrically connecting the third inner circle 319 to the e-textile wiring 325 through the fabric. The base 360 also includes a magnet 335 disposed on a second side of the fabric 320. As illustrated, the magnet 335 is held between a substrate 330 for the e-textile wiring 325 and a backing material 340. In an example, the magnet 335 is permanently bonded to the fabric 320. In an example, the permanent bond is created by an adhesive (e.g., glue, epoxy, etc.) bonding the magnet 335 directly to the fabric 320, or to a material otherwise bonded to the fabric 320. For example, the magnet 335 may be glued to the backing material 340 which is in turn bonded (e.g., via adhesive) or sewn to the e-textile wiring substrate 330 which is itself bonded to the fabric 320. In an example, the magnet 335 is disposed in a sealed fabric pocket to permanently bind it to the fabric.

In an example, the outer circle 316 includes an adhesive to bond to the first side of the fabric 320. In an example, the adhesive is activated via heat. In an example, the adhesive is activated by pressure. In an example, the adhesive is activated by heat and pressure.

In an example, the first trace is arranged to electrically connect to a positive pole of the battery 310. Thus, the first inner circle 317 is arranged to receive a positive pole of the battery 310 via the conductive ring 210. In an example, the second trace is arranged to electrically connect to a negative pole of the battery. Thus, the third inner circle 319 is arranged to receive the negative pole 220 of the battery 310 directly from the battery 310.

FIGS. 4A-4D illustrate a technique for assembling a battery housing base, according to an embodiment. FIG. 4A illustrates the outer circle 405 of the seat that is perforated. The outer circle 405 may be bonded to the underlying fabric via an adhesive or sewn to the underlying fabric. In FIG. 4B, the first inner circle 410 and the third inner circle are connected to respective traces and drawn through perforations in the outer circle 405. In FIG. 4C, the first inner circle 410 and third inner circle are folded over and onto the outer circle 405 and bonded to the outer circle 405 (e.g., heat pressed). In this example, after folding the first inner circle 405 and the third inner circle onto the outer circle 405, the outer circle material forms both the outer circle 405 and the second inner circle, providing electrical insulation between the first inner circle 405 and the third inner circle. FIG. 4D illustrates the completed seat with the concentric circles that alternate between insulating material and conductive material. Here, the conductive material is shaded.

FIGS. 5A and 5B illustrate attaching a magnet to an e-textile, according to an embodiment. FIG. 5A illustrates the battery 505 being placed in a pocket 510 which is disposed opposite to the seat (illustrated as dashed lines).

The method 600 may be extended by providing a magnet disposed on a second side of the fabric. In an example, the magnet is bound to the fabric permanently. In an example, binding the magnet to the fabric includes placing magnet into pocket and sealing the pocket.

At operation 715, a conductive cap is provided. The conductive cap is arranged to engage the conductive ring to hold a battery against the insulating layer and the conductive ring. The conductive cap is also arranged to electrically connect a second terminal of the battery to the conductive ring when the battery is placed within the housing.

Examples, as described herein, may include, or may operate by, logic, components, or mechanisms in the machine 800. Circuitry (e.g., processing circuitry) is a collection of circuits implemented in tangible entities of the machine 800 that include hardware (e.g., simple circuits, gates, logic, etc.). Circuitry membership may be flexible over time. Circuitries include members that may, alone or in combination, perform specified operations when operating. In an example, hardware of the circuitry may be immutably designed to carry out a specific operation (e.g., hardwired). In an example, the hardware of the circuitry may include variably connected physical components (e.g., execution units, transistors, simple circuits, etc.) including a machine readable medium physically modified (e.g., magnetically, electrically, moveable placement of invariant massed particles, etc.) to encode instructions of the specific operation. In connecting the physical components, the underlying electrical properties of a hardware constituent are changed, for example, from an insulator to a conductor or vice versa. The instructions enable embedded hardware (e.g., the execution units or a loading mechanism) to create members of the circuitry in hardware via the variable connections to carry out portions of the specific operation when in operation. Accordingly, in an example, the machine readable medium elements are part of the circuitry or are communicatively coupled to the other components of the circuitry when the device is operating. In an example, any of the physical components may be used in more than one member of more than one circuitry. For example, under operation, execution units may be used in a first circuit of a first circuitry at one point in time and reused by a second circuit in the first circuitry, or by a third circuit in a second circuitry at a different time. Additional examples of these components with respect to the machine 800 follow.

In alternative embodiments, the machine 800 may operate as a standalone device or may be connected (e.g., networked) to other machines. In a networked deployment, the machine 800 may operate in the capacity of a server machine, a client machine, or both in server-client network environments. In an example, the machine 800 may act as a peer machine in peer-to-peer (P2P) (or other distributed) network environment. The machine 800 may be a personal computer (PC), a tablet PC, a set-top box (STB), a personal digital assistant (PDA), a mobile telephone, a web appliance, a network router, switch or bridge, or any machine capable of executing instructions (sequential or otherwise) that specify actions to be taken by that machine. Further, while only a single machine is illustrated, the term “machine” shall also be taken to include any collection of machines that individually or jointly execute a set (or multiple sets) of instructions to perform any one or more of the methodologies discussed herein, such as cloud computing, software as a service (SaaS), other computer cluster configurations.

The machine (e.g., computer system) 800 may include a hardware processor 802 (e.g., a central processing unit (CPU), a graphics processing unit (GPU), a hardware processor core, or any combination thereof), a main memory 804, a static memory (e.g., memory or storage for firmware, microcode, a basic-input-output (BIOS), unified extensible firmware interface (UEFI), etc.) 806, and mass storage 821 (e.g., hard drive, tape drive, flash storage, or other block devices) some or all of which may communicate with each other via an interlink (e.g., bus) 808. The machine 800 may further include a display unit 810, an alphanumeric input device 812 (e.g., a keyboard), and a user interface (UI) navigation device 814 (e.g., a mouse). In an example, the display unit 810, input device 812 and UI navigation device 814 may be a touch screen display. The machine 800 may additionally include a storage device (e.g., drive unit) 816, a signal generation device 818 (e.g., a speaker), a network interface device 820, and one or more sensors 821, such as a global positioning system (GPS) sensor, compass, accelerometer, or another sensor. The machine 800 may include an output controller 828, such as a serial (e.g., universal serial bus (USB), parallel, or other wired or wireless (e.g., infrared (IR), near field communication (NFC), etc.) connection to communicate or control one or more peripheral devices (e.g., a printer, card reader, etc.).

Registers of the processor 802, the main memory 804, the static memory 806, or the mass storage 816 may be, or include, a machine readable medium 822 on which is stored one or more sets of data structures or instructions 824 (e.g., software) embodying or utilized by any one or more of the techniques or functions described herein. The instructions 824 may also reside, completely or at least partially, within any of registers of the processor 802, the main memory 804, the static memory 806, or the mass storage 816 during execution thereof by the machine 800. In an example, one or any combination of the hardware processor 802, the main memory 804, the static memory 806, or the mass storage 816 may constitute the machine readable media 802. While the machine readable medium 822 is illustrated as a single medium, the term “machine readable medium” may include a single medium or multiple media (e.g., a centralized or distributed database, and/or associated caches and servers) configured to store the one or more instructions 824.

The term “machine readable medium” may include any medium that is capable of storing, encoding, or carrying instructions for execution by the machine 800 and that cause the machine 800 to perform any one or more of the techniques of the present disclosure, or that is capable of storing, encoding or carrying data structures used by or associated with such instructions. Non-limiting machine readable medium examples may include solid-state memories, optical media, magnetic media, and signals (e.g., radio frequency signals, other photon based signals, sound signals, etc.). In an example, a non-transitory machine readable medium comprises a machine readable medium with a plurality of particles having invariant (e.g., rest) mass, and thus are compositions of matter. Accordingly, non-transitory machine-readable media are machine readable media that do not include transitory propagating signals. Specific examples of non-transitory machine readable media may include: non-volatile memory, such as semiconductor memory devices (e.g., Electrically Programmable Read-Only Memory (EPROM), Electrically Erasable Programmable Read-Only Memory (EEPROM)) and flash memory devices; magnetic disks, such as internal hard disks and removable disks; magneto-optical disks; and CD-ROM and DVD-ROM disks.

The instructions 824 may be further transmitted or received over a communications network 826 using a transmission medium via the network interface device 820 utilizing any one of a number of transfer protocols (e.g., frame relay, internet protocol (IP), transmission control protocol (TCP), user datagram protocol (UDP), hypertext transfer protocol (HTTP), etc.). Example communication networks may include a local area network (LAN), a wide area network (WAN), a packet data network (e.g., the Internet), mobile telephone networks (e.g., cellular networks), Plain Old Telephone (POTS) networks, and wireless data networks (e.g., Institute of Electrical and Electronics Engineers (IEEE) 802.11 family of standards known as Wi-Fi®, IEEE 802.16 family of standards known as WiMax®), IEEE 802.15.4 family of standards, peer-to-peer (P2P) networks, among others. In an example, the network interface device 820 may include one or more physical jacks (e.g., Ethernet, coaxial, or phone jacks) or one or more antennas to connect to the communications network 826. In an example, the network interface device 820 may include a plurality of antennas to wirelessly communicate using at least one of single-input multiple-output (SIMO), multiple-input multiple-output (MIMO), or multiple-input single-output (MISO) techniques. The term “transmission medium” shall be taken to include any intangible medium that is capable of storing, encoding or carrying instructions for execution by the machine 800, and includes digital or analog communications signals or other intangible medium to facilitate communication of such software. A transmission medium is a machine readable medium.
